Abstract

The Makeham distribution has been used to describe human mortality and establish actuarial tables. The hazard function is defined by @m(t)=A+BC^t, we use the least squares type estimation to estimate the parameters of Makeham distribution in this paper. Seven cases are considered, when A, B, C are known or unknown, respectively. Also, we evaluated the mean square errors of these estimators.
